Parking lock releasing device

Abstract

A transmission control device of a vehicle has a shifting body and detects the operating state of the shifting body. The transmission control device shifts the connecting state of the transmission based on the detection result. A parking lock state releasing apparatus for the vehicle includes a releasing switch, which is located in a passenger compartment. An ignition drive device generates gas by causing ignition in response to operation of the releasing switch. The parking lock state of the transmission is changed to the release state using the pressure of the gas.

What is claimed is:  
     
       1. A parking lock state releasing apparatus for a vehicle with a transmission control device, wherein the transmission control device has a shifting body and detects an operating state of the shifting body, wherein the transmission control device shifts a connecting state of a transmission based on the detection result, the apparatus comprising: 
       a parking lock member, which is located in the transmission, wherein the parking lock member mechanically locks wheels of the vehicle by means of the transmission;  
       a power transmitting member, wherein the power transmitting member has a proximal end connected to the parking lock member of the transmission and a distal end connectible to a conventional movable member provided in the vehicle; and  
       a switch, which connects the movable member to the power transmitting member when manipulated;  
       wherein the power transmitting member is driven in response to operation of the movable member when the movable member is connected to the power transmitting member by the switch, and the parking lock state of the transmission is changed to the release state in accordance with the driving of the power transmitting member, wherein the switch can only be manipulated when normal functioning of the transmission control device is hampered.  
     
     
       2. A parking lock state releasing apparatus for a vehicle with a transmission control device, wherein the transmission control device has a shifting body and detects an operating state of the shifting body, wherein the transmission control device shifts a connecting state of a transmission based on the detection result, the apparatus comprising: 
       a parking lock member, which is located in the transmission, wherein the parking lock member mechanically locks wheels of the vehicle by means of the transmission;  
       a power transmitting member, wherein the power transmitting member has a proximal end connected to the parking lock member of the transmission and a distal end connectible to a movable member provided in the vehicle; and  
       a switch, which connects the movable member to the power transmitting member when manipulated;  
       wherein operation force of the movable member is amplified by a lever effect when the movable member is connected to the power transmitting member by the switch and the movable member is operated, the power transmitting member is driven by the amplified force, and the parking lock state of the transmission is changed to the release state by the power transmitting member, wherein the switch can only be manipulated when normal functioning of the transmission control device is hampered.
